What is python? 

python is an easy-to-learn, future-proof programming language.
It is particularly characterized by a large community and many libraries.

You can download python here:
https://www.python.org/downloads/

You can find the most python libarys at the python package index:
https://pypi.org/
  
I recommend you to start with a simple Hello World programm:
  
print("Hello World!")
